Harrington's disqualification from lasts month's Abu Dhabi Championship led world governing bodies, the R&A and USGA, to review Rule 6-6b that deals with signing for an incorrect score.

It has been suggested a local rule might be introduced at professional events making it possible for officials to amend a scorecard retrospectively if a player had no way of knowing a penalty was due at the time.

Harrington believes finding the correct wording for an addendum to one of the most important rules in golf would be "a lot more difficult than it sounds.

"On the face of it, you could sit down over dinner and you come up with a number of ways to change the rules," he explains: "But when a committee actually sits down and examines it, I think they will find it very difficult to find a new rule that covers all angles.

"Maybe the best suggestion, albeit a bit awkward to do, would be have a video ref sitting there, and he signs off at the end of the day and that's it," the Dubliner adds.

"There are many options, but, subjectively, that would be fine, certainly in professional events, where they do have the cameras and the ability to have qualified professionals ruling on this all the time," says Harrington, who's in action once again today with JP McManus at his side in the AT&T National Pro-Am at Pebble Beach.
